Job ter Haar studied cello at the Royal Conservatory in The Hague with René van Ast, Lidewij Scheifes and Anner Bijlsma. During and after his studies he specialized in chamber music. With his baroque ensemble, Musica ad Rhenum, he has recorded many CDs, which distinguish themselves through the use of historical tempi and rubato. In recent years he has delved even further into classical and romantic style. Above all, his interest is in the use of early 19th-century expressive tools. Next to his performing career, Job ter Haar is working as a research coach at Codarts Rotterdam. Currently he is pursuing a PhD at the Royal Academy of Music in London about the performing style of the 19th-century cello virtuoso Alfredo Piatti.
